similar to: there is no "xls" reader in R?

Hi, Suppose I have: for(i in 1:100000) rnorm(100000) (just a fake example, as my actual example is too long) Is it possible to get the loop to print out i each time it has run? Something like: for(i in 1:100000) { print(i) rnorm(100000) } will only print i after the loop is completed. But if I want to print out i whenever it re-enters the loop, is it possible (so I know how

I started to learn the R language, but I didn't suceed to use an external file. Let say that I have an excel file called "test1.xls" in the directory "C:/program files/R/rw2000/external_files" that looks like that: name mark yair 80 yosi 70 ... In the appropriate directory I wrote this: x<-read.delim("test1.xls") or this:

Hi, Suppose I've got a matrix, and the first few elements look like "x1 + x3 + x4 + x5 + x1:x3 + x1:x4" "x1 + x2 + x3 + x5 + x1:x2 + x1:x5" "x1 + x3 + x4 + x5 + x1:x3 + x1:x5" and so on (have got terms from x1 ~ x14). If I want to replace all the x1 with i7, all x2 with i14, all x3 with i13, for example. Is there an easy way? I tried to put what I want

I'm looking for a Windows distribution of TeX that works with R, after a few years' absence from Windows. On Duncan Murdoch's Rtools page fptex is still recommended, but it turns out that fptex is "defunct" as of May 2005, see http://www.metz.supelec.fr/~popineau/xemtex-7.html So, what is suggested? TUG (tug.org) recommends something called proTeXt, which is said to be

Hi to all, I am a PH.D Student doing statistical analysis. I am totally new to R. I previously use Stata and am changing into R. I ususally do with logit regression with binary dependent variable (war occurence:1 or 0). I just want to know command to do that. More sepcifically, Let say, my Y is war occurence (occur=1, otherwise 0). And my independent variables (Xs) are trade, democracy,

Its just a simple question I guess: I have a vector with missing information like x<-c(0,1,31,131,NA,133,NA,310,NA,112,3,1,2,93) How can I make a vector like this no missing in it. I used the x[x<0] commabd and tried some more, with no success. thx Korbinian

Hello.. I am pretty new for R, but if I understand it correctly, when R read data by doing something like "d <- read.table("/dev/stdin")", it read entire data first then start processing.. Is there anyway I can tweak R around so that it will start processing as data comes and not load everthing on memory at once? The reason for this is because we have a case where

Hi, I am trying to find out a collinearity in explanatory variables with alias(). I creat a dataframe: dat <- ds[,sapply(ds,nlevels)>=2] dat$Y <- Response Explanatory variables are factor and response is continuous random variable. When I run a regression, I have the following error: fit <- aov( Y ~ . , data = dat) Error in "contrasts<-"(`*tmp*`, value =

dear all. Would someone be kind and willing to explain the code below for a person who has never used R? ( that is if one has enough time and inclination) It implements gillepsie's stochastic algorithm for Lotka Volterra model. What would help me tremendously is to see the breakdown of the line by line code into plain english. thanks for any insights or other comments. sean
